The Sinister Six are a team of supervillains who have joined together on multiple occasions to try and defeat their shared nemesis Spider-Man. The group typically bands together for a short time to try and reach their common goal, then breaks apart when they are defeated and later are reformed under the same name when different foes want to attempt a group effort again.
The members of the team change with each reformation of the team, with Doctor Octopus, Electro, and the Vulture being the most frequent reoccurring members. Many derivative groups have formed using similar names and goals, including the "Sinister Seven", the "Sinister Twelve", and the Savage Six.
